Actual manufacturer product view. Illustrated supplies or instruments show an application; refer to the stated order unit for the item supplied.

Track several tasks without several timers

Four independent channels let one compact unit serve several timed activities. Assign a channel to each task before starting, and keep the assignment visible in your working notes. The audible and visual alarms provide two forms of indication, while the small housing can remain near the operator rather than occupying a large section of bench.

Choose the mode before starting

The side switch selects clock, count-up, count-down or programming operation. The instruction manual describes setting a countdown with the HR, MIN and SEC buttons and starting or pausing it with START/STOP. Check the displayed mode and channel against the intended task before each run; a remembered setting is not a substitute for confirming the next timing interval.

Understand what happens at zero

The manual describes a 60-second audible alarm and a flashing TIME’S UP indication when a countdown finishes. It also describes an overtime count-up, allowing the user to see elapsed time after the alarm point. This can help distinguish an on-time response from a delayed one, but a timer reminder does not itself stop a reaction or control equipment.

Position it for the person using it

Use the spring clip or magnetic back to keep the display accessible without balancing the timer among sample containers. The housing measures 6.1 × 7.1 × 2.5 cm and uses one included LR44 1.5 V battery. Choose a whiteboard timer instead when written task labels beside the timer are more important than pocket portability.
